My invention relates to improvements in candy machines which areparticularly adapted for use in separating cut caramel or marshmallows.An object of the invention is to provide means for separating the cutmaterial by gripping and pulling it from the mass While it is beingmoved upon an endless belt or suitable conveyor.

The invention consists of a separating structure having moving partsoperated at dierent speeds, as will be more fully described in thefollowing specification and shown in the accompanying drawings, inwhich:

Fig. 1 is a plan view of the invention.

Fig. 2 is a side elevational view showing the conveyor belt and drumrotating drives.

Fig. 3 is a detail elevational view of the separating mechanism.

Fig. 4 is a fractionated plan view showing the driving train.

In the drawings like characters of reference indicate correspondingparts in each gure.

The numeral I indicates a frame consisting of uprights 2, longitudinalmembers 3 and transverse members 4, 5 and 5. Supported from one of thelongitudinal members 3 is a reduction gear 1 which is belt driven from amotor 8 and a pulley 9 which drives a pulley Ill by means of a belt I I.'Ihe pulley I0 is fitted to a transverse shaft I2, which shaft and asimilar shaft I3 are fitted with rollers I4 for the purpose ofsupporting an endless conveyor belt I5. Adjacent the shaft I3 is a pairof standards I6 carrying fixed bearings I1 for transverse idler shaftsI8 and I9. These shafts are relatively small and are relatively close toeach other to dene a small intermediate gap 20 through which smallcaramels may not drop. 'Ihe idler shaft I8 is mounted above the rollerI3 and is engaged by the conveyor belt I5. Vertically adjustable bearingblocks 2I are fitted in the standards I6 and adjusting screws 22 areprovided for adjusting their position vertically. Journalled in thebearing blocks 2I are shafts 23 and 24 fitted with rollers 25 and 26respectively.

The shaft 23 is fitted with a pulley 21 and is belt driven from a pulley28 upon a transverse shaft 29 which in turn is driven by a cross belt 30carried by pulleys 3I and 32 fitted to the shafts 29 and I2respectively, so that the peripheral travel of the roller 25 of theshaft 23 will be at the same speed as the conveyor belt I5.

The shaft 29 is tted with a cone pulley 33 and through a belt 34 drivesa reversely disposed cone pulley 35 which is tted upon a counter shaft36. The shaft 36 is fitted with a pulley 31 at one end and a pulley 38at the other, the pulley 38 being connected by a belt 39 to a pulley 49which is secured to the shaft 24. The idler shaft I9 coacts with aroller 43 upon a shaft 44 and an idler shaft 45 carried byinwardlyproject- 5 ing arms 46 to drive an inclined conveyor belt 41.

The conveyor belt 41 is driven by the pulley 31 upon the shaft 36 acrossed belt 49 and a pulley 59 upon the roller shaft 44. The crossedbelt 49 causes the inclined conveyor belt 41 to travel in 10 the samedirection as the conveyor belt I5.

The driving belt 34 running upon the cones 33 and 35 is moved as desiredby a belt shifter 5I of any suitable type and the drive is soproportioned as to cause the peripheral travel of the 15 roller 26 andthe inclined conveyor bracket 41 to be selectively greater than thetravel of the conveyor belt I5.

Driven from the reduction gear 'I is a shaft 52 extending through to thedelivery end of the 20 machine and having at its free end a pulley 53,and mounted longitudinally of the frame I is an inclined shaft 54 fittedWith a pulley 55 driven from the pulley 53 by a belt 56. The shaft 54 isfitted with one or more spiders 51 which support 25 a conical drum 58having a helix 59 on its inner periphery which urges material droppingonto the walls of the drum towards its inner end Where the drum isprovided with ights 60 for the purpose of raising the material receivedfrom the 30 helix 59. Supported concentrically inside the drum 58 is aconical screen 6I which is also provided on its inner periphery with ahelix 62. This helix tends to urge material dropped from the inclinedconveyor belt 41 through the screen 35 to discharge from the outer endof the drum 58. Rockingly mounted above the transverse frame member 5 isa chute 63 which extends at its upper end into the drum and under theoverhanging flights. This chute is carried upon a 40 shaft 64 and uponthe shaft is an arm 65 which is swung in one direction by a cam Wheel 66mounted upon the shaft 44 and is swung in the opposite direction by aspring 61.

Assuming that slabs of marshmallow are to be 45 separated intoindividual cubes and coated with roasted nut, a quantity of granulatednut is put into the drum 58 and the machine is set in motion. The slabswhich have been previously cut into cubes but remain in slab form byinherent 50 adhesion are placed upon the conveyor I5 preferablydiagonally and as each slab reaches the roller 25 it is gripped therebyand is held down flat upon the conveyor and is then fed through to theinclined conveyor 41 and the roller 26, 55

both of which are moving at a higher speed than the conveyor I5 and theroller 25. The increase of speed above referred to stretches themarshmallow until a cut in the slab is above the gap 2B, when thetension causes the cubes to separate. Granulated nut is fed onto thechute 63 which is continually vibrating and gravitated onto themarshmallow as it passes across the gap, some of itdropping onto thevertical cut surfaces of the marshmallow. The separation of the cubesactually takes place after the cut has passed over the gap 20, hencelittle or no coating material falls through said gap. The separatedcubes roll down the inclined conveyor and are dropped into the conicalscreen 6| where they are tumbled and urged by the helix 62 to discharge,while being sprinkled with granular nut falling from the inclinedconveyor 47 and from the ights 60 and also from some falling from 20 thehelix 59.' The sprinkling of the coating Will fbecome less towards theouter` end of the drum -and the-.dropping of coating material from thecubes will decrease as the cubes progress through the screen. Thedropped coating material is returned by the helix 59 and is carried upto the invert of the drum by the flights 60 to again be dropped onto thechute 63 for coating new material.

What I claim as my invention is:

In a machine for separating cubes from a candy slab, a vhorizontalconveyor comprising a pair of spaced rollers and an endless conveyorbelt, a roller directly over one of the rst named rollers adapted topress down upon the candy slab and hold it flat upon the belt at thepoint of discharge, an inclined conveyor belt adapted to receive thecandy from the rst named conveyor belt and a roller mounted above thereceiving end of the second named conveyor and below the axis of thecandy slab pressing roller, said last named roller being driven andadapted to break down the leading edge of the slab.
